My Spline Mesh's comporting weird

i made a rollercoaster for a VR project im working on, but the rotation of my spline mesh wasn’t following my spline point’s, so i played around the set up dir and ended up like this, now the start of every spline mesh instance is a bit funny (some more than others). i dont know what to do, i already had avoid doing loops cuz i knew UE’s spline mesh tends to go nuts on that, but now my turns are also a mess
